The oldest and most reliable sign of a trend change in the markets I’ve noticed is when you’re in a bull market and the markets open higher but close lower than that. Alternatively, in a bear market, we open lower and close much higher.

Shorts are piling in, valuations are cheap, — but can't they see the rot? 📉 FII Derivatives — 21 May 2026 FII Futures 🔴 Net SHORT Contracts -231,190 (26-session streak) 5d avg -187,254 PCR 0.95 → Neutral Valuation PE 20.4 · 14th pctile · below 1Y avg (22.1) 💬 FII futures continue to bet against a Nifty breakout, as they remain NET SHORT despite historically cheap valuation, pointing to a potential continuation of the trend unless FII positioning breaks through the neutral PCR, watch 26 sessions. What macroeconomic event or policy change could flip FIIs short? #Nifty50 #NSE #MarketValuation #FIIShort #FIILong

Stocks are satta, but betting on Rain is a hedge ?

@CommerceGuruu He said his mom agreed to sell 150gm gold considering that’s 1% of what she has. She’s got 15kgs of Gold or 22.5Cr worth of physical Gold ?????!

As per this logic, I request every Indian to buy Rs100 worth of Nifty and we will hit upper circuit tomorrow What clowns do we have

Shorts see 25% drop, but market price still cheap — something has to give 📉 FII Derivatives — 20 May 2026 FII Futures 🔴 Net SHORT Contracts -222,520 (25-session streak) 5d avg -187,254 PCR 1.14 → Neutral Valuation PE 20.41 · 14th pctile · below 1Y avg (22.1) 💬 FII's 25-session net short position is diverging from valuation signals, as a low Nifty PE of 20.41 (historically cheap, below 5-year avg) suggests buyers are undervaluing the market, and FII is short, which is usually a bullish trigger for Nifty prices. What is the imminent catalyst forcing FIIs to rebalance their shorts? #Nifty50 #NSE #MarketValuation #FIIShort #FIILong

The age-old debate between active and passive investing has been a topic of discussion among investors for decades. At its core, the question is simple: can a skilled manager consistently beat the market, or is the market itself the best guide for investment decisions? As a value investor, I've always been drawn to the latter perspective, and the evidence from the Indian stock market is compelling. The NIFTY Next 50 index, for example, has been a rock-solid performer over the past five years, delivering a total return of around 16.5% compared to some actively managed mid-cap funds which have returned around 12-15%. This disparity in performance is not just a result of luck, but rather a testament to the efficiency of the market. By tracking the market as a whole, the NIFTY Next 50 index has been able to capture the benefits of compounding and diversification, resulting in a low expense ratio of 0.05% and a dividend yield of around 1.2%. While the index's price-to-earnings ratio of around 30 may seem relatively high, it's essential to consider the broader market context and the fact that the index has been a steady performer over the long term. As a retail investor, my advice would be to adopt a similar approach by investing in index funds. Rather than trying to pick individual stocks or actively manage your portfolio, consider allocating a significant portion of your investments to a broad market index fund. This will provide you with broad market exposure, diversification, and the benefits of compounding, all while keeping your costs low. By following this simple rule, you'll be well on your way to creating a stable and long-term investment portfolio. #IndexInvesting #

@MarioNawfal How far are we from Jurassic Park?

🇺🇸 A Texas biotech company just hatched 26 live chicks from 3D-printed artificial eggs with no shells and no hens. First time in history a complete bird embryo developed in a fully artificial system. And that's just the warm-up. Colossal Biosciences is using this same tech to bring back the South Island giant moa: a 12-foot-tall, 250 kg bird that went extinct 600 years ago. No surrogate exists on Earth big enough to hatch one. So they built the technology to do it without one. De-extinction just went from science fiction to a construction project.

Is it just me or have all the LLMs become more conservative with their tokens? How many of us would actually pay the 20k per month for the prime version of these tools ?

@InvestRepeat Might be interesting to see if they began lagging behind since Adani stocks went into correction. If you think about it they’ve had a huge exposure to Adani and Reliance stocks at one time

@InvestRepeat Probably cus of Adani getting a clean chit in the US

quant Mutual Fund has made a sudden comeback in last month. Their flexi cap scheme is now up more than 7% in last 1 year. During the same time HDFC and PPFAS Flexi Cap are negative. Do you think quant is making a comeback? Or its just a temporary rise?

The margin of safety is a timeless investing principle that has been tested across various market cycles. It's the idea that a buyer can purchase an asset at a price significantly lower than its true value, providing a cushion against potential losses. When this principle is applied, it's like buying insurance against the inevitable - the market's inherent volatility and unpredictability. Larsen & Toubro (L&T) is a classic example of this principle in action. In 2013, the company's stock price plummeted by over 20% to around ₹800, presenting a significant margin of safety for investors. Given its intrinsic value was estimated to be around ₹1,200, L&T's stock became an attractive buy, especially considering its strong financials and low debt levels. The company's ability to generate high returns on equity of around 15% has helped it recover from the crisis, with its P/E ratio of around 25 providing a solid foundation for its stock price. For retail investors, applying the margin of safety principle requires a disciplined approach. When evaluating a potential investment, ask yourself: "Can I buy this stock at a price significantly lower than its true value?" If the answer is yes, then you've got a margin of safety. Be willing to wait for the right opportunity, and don't be swayed by short-term market fluctuations. With patience and a long-term perspective, you can reap the rewards of a margin of safety. #InvestingWithMarginOfSafety #ValueInvesting #LongTermGrowth

The reason this sharp bounce happened is that Korea Market Authority activated the "Sidecar" mechanism that, in simple terms, unplugs any algorithmic trading so retail can keep filling their bags without momentum algorithms dumping stocks making them second-guess their bid

@aravind Do you see the crude and Hormuz normalize or is 100 DBL the new normal ?

It's May. It's time. Cuba must prepare for US action soon if they don't want to leave China/Russia alliance as the US wants. Doesn't matter what they do, an "attack on US territory like Guantanamo Bay from Cuba" news can be used to invade and take over like VZ. Good luck, Cuba.

@zeptocares how do I complain if your email keeps bouncing

The pursuit of wealth creation has long been a subject of debate among investors, with some advocating for the importance of frugality and saving, while others champion the value of taking bold risks and investing heavily in one's business. In our pursuit of wealth, it's worth considering whether the latter approach is truly the key to unlocking substantial returns. Consider the story of Flipkart, the Indian e-commerce company that was acquired by Walmart for $16 billion in 2018. The company's founders, Sachin and Binny Bansal, took a bold risk by investing heavily in their business, resulting in a valuation increase from $1.4 billion in 2013 to $16 billion in 2018, a gain of 1,043%. This massive payoff is a testament to the power of prioritizing big wins over frugality. By taking a long-term view and investing in their business, the Bansal brothers were able to achieve a level of success that few others have matched. For retail investors, the moral of this story is clear: it's often the big wins that drive long-term wealth creation, rather than the small savings that might seem more appealing. By adopting a similar mindset and taking calculated risks, retail investors can position themselves for significant returns. By focusing on the potential for big wins, rather than trying to squeeze every last penny out of every investment, investors can unlock a level of wealth creation that was previously unimaginable. #ValueInvesting #WealthCreation #LongTermFocus

@InvesysCapital I’ve had a theory that BRK only managed to generate significant alpha while we had information asymmetry. Ever since tech evolved and information became easily available it’s been lagging behind

Much has been said of Berkshire's cash pile & how it is underperforming #SPX by wide margin. There is pattern to it. In last stages of major bullrun BRK underperforms the SPX but when market tops & crisis sets in BRK outperforms SPX by wide margin However past couple of decades despite these small stages of outperformance, BRK is not generating any alpha over SPX like pre 2000

@biharigurl Let’s pls start with suhraverdy avenue

Roads like Prince Anwar Shah, Prince Golam Mohammed Shah road in Kolkata should be renamed 🙏 Requesting West Bengal Government to do so...
