Sharing my risk-adjusted returns YTD. Here are the takeaways:

📈 Outperforming S&P 500 by ~11%
🧠 Low drawdown
⚖️ High risk-adjusted return
🔍 Very little correlation to S&P 500 (strategy is hunting idiosyncratic alpha, not riding the market beta wave)

If you think I'm not for real or a shyster just unfollow me. It's *genuinely* that simple.

Buddy, I'm offering all this for free. This is my *hobby*, not my *job* — I'm under no obligation to you. It's a fun, "build in public" hedge fund or sorts. It's for fun. Period. I made enough money off my last business, I don't *need*, by any means, to sell anything.

Here's the full article on my March/early-April fund performance:

And, again, I'm not charging you anything to follow along, nor selling you anything. If you don't currently trust me, no worries. I get it. Perhaps in the future.

But I can't give an exact date, because, as you know, the markets are chaos right now and learning how to trade and make this thing profitable for *myself* is my first priority. Education and dissemination is my second priority. I only have so much time in the day.

Hey Michael thanks for following up. This is still very much a WIP. I'm not selling anything to you, so there's literally no risk to you unless you choose to invest your money (which I wouldn't recommend anyway).

I hope to have something more verifiable up and running in the next 1-3 months.

This is my first year, actually!

yfinance's default MultiIndex is a nightmare for multiple stocks

2 tickers = 10 columns

I prefer a row-based index
- Always 5 columns (OHLCV)
- Easier indicator calculations
- Debuggable without eyestrain

Thank you for the feedback, Michael.

In general, yes, I'd like to start publishing trades as they happen. Typically I author articles explaining them and/or do a post-mortem but obviously that can't be done in real-time.

I'll look into services to help with the transparency.
