One of the most underrated skills in trading is patience.

Breaking: My wife's children's book is out today! It's called Charts for Babies, and is available anywhere you buy books. We thought, what better way to celebrate the big moment than to collaborate on a post together? In today's very special newsletter, @TheRialMichelle shares a visual guide to getting out of a creative slump. You'll get a glimpse into Michelle's brilliant mind. It's genuinely inspiring and useful, and is for anyone trying to create something today. Read it right now or bookmark it for the next time you get stuck: lennysnewsletter.com/p/a-visual-gui…

One of my favourite features from @KoyfinCharts is the transcript summary button. Once you click the button, Koyfin summarises quarterly financial performance, KPIs, geographical performance, strategy and execution, future guidance outlook, outlines any vital risks that management noted, and finally, summarises the key Q&A of the call. Great stuff!

Dev Shah@0xDevShah·
1 in every 5 founders I meet in the Bay Area is building an observability platform for agents. There are so many observability platforms, yet the least mature part of building an agent is still telemetry. Everyone is trying to solve the wrong problem with observability. Visibility is the easiest piece. The hard part is analyzing and understanding what you’re observing. I’ve spoken to teams recording 100k+ traces every single day. What are they doing with those traces? Literally nothing. Because it’s impossible to read and summarize 100,000 traces at any human scale. So stop vibecoding those stupid dashboards, and how about you re-center the problem from first principles?

@RShore19 @Bakerman_06 In the screener, you can specify the last price range, and search for stocks near their daily highs. Is that what you mean?

@paulg @patrickc GOOGL's revenue growth was more than 2x AAPL and MSFT, but trades at the lowest price/sales multiple

Paul Graham@paulg·
@patrickc Has their revenue grown at the same rate? If so perhaps there's some limit at which big companies can grow and they're all at it. If not, then there's presumably some kind of contagion of market cap expectations between what investors view as similar companies.

These companies are ostensibly in totally different businesses and yet seem to exhibit the same growth dynamics. What's the explanation? (Pictured: ~$200B -> ~$3T.)

@koyfman love the product. When can we expect real time or near real time updates for Europe? Many including me would be paid subscribers with this one change.

@KoyfinCharts I thought the April 1st joke would be that Portfolios are finally available in the iOS mobile app :)

@KoyfinCharts Change in two percentages (eg 5% to 10%) should be measured in percentage points (eg 5pp). Change in two multiples (eg 5x to 10x) should be measured in multiple points (eg 5mp). Team A

If a PE multiple expands from 5x to 10x How would you quantify or represent the change?
