285% Returns: My H1 2025 Breakdown

Hey everyone,

What a wild first half of 2025! My portfolio is up 285% while the S&P 500 managed just 7%. Here's how it went down and what I learned.

My Current Holdings

$TMDX, $IREN, $LODE, $TSSI, $PSIX, $TGEN, $FTEK, $DTEAF, $URLOF, $NURS.V, $ZOMD.V

My Top 3 Winning Trades

1. TransMedics ($TMDX) - Following the Data

I'd been tracking TransMedics TMDX 0.00%↑ closely using my internal dashboard at https://jinacapital.com/tmdx-tracker. My analysis showed Q1 revenue would hit around $145M while Wall Street was expecting $123M. With that kind of confidence, I loaded up the stock and played some options too around earnings. Those options printed nearly 300 %

2. The Government Contracting Play

This one was pure connecting the dots. Treasury Secretary Bessent mentioned on the All-In podcast (March 18) that 98% of Booz Allen Hamilton's revenue comes from government contracts. Then Accenture's earnings call (March 20) suggested DOGE might hurt their growth, and their stock crashed and Booz Allen Hamilton options exploded 6,000%.

When Booz Allen Hamilton BAH 0.00%↑ reported earnings on May 23, I shorted both companies with options. Another 300% winner.

3. Riding the Ethereum Treasury Wave

I'd been watching crypto shell companies pivot to Ethereum treasury strategies. After seeing MFI 0.00%↑ (which is still a speculation in play) and SBET 0.00%↑ (which went from $2 to $70 in under a week on a $450M raise before crashing), I had conviction that the next Ethereum treasury company would hit at least 1x their etherium raise in market cap.

When BMNR 0.00%↑ announced their Ethereum treasury strategy and raised $250M, the stock rocketed from $4.50 to my target range within days. I bought heavy at $21 and sold everything at $56 when it hit my risk level

Real talk: I don't think Ethereum-based stablecoins will last 5-10 years due to gas fees (even USDT is moving away from Ethereum because people prefer Tron or Solana's zero fees). But for the next 6 months, this narrative is going to print money.

My Biggest Miss

CoreWeave ($CRWV)

I'd tested their cloud platform and it was insanely good. Even, semianalysis rated them as top tier over every hyperscalar. They had OpenAI deals, NVIDIA backing them against the big cloud giants (Amazon, Google, Microsoft), and a once-in-a-generation founder. But the financials didn't make sense to me at the IPO. This one's definitely going in my anti-portfolio hall of shame.

Where I Got Burned

Liberation Day Hedge Disaster

I went into Liberation Day with hedges and was up 5% after hours. Thinking it was just an overnight reaction, I closed my hedges the next morning. Then came the bloodbath. I had to reduce positions, including partially selling TSSI 0.00%↑ at $8 (it's at $30 now) and PSIX 0.00%↑ at $20 (currently $78).

Lesson learned: keep your hedges during uncertain times.

What I'm Doing Next

1. AI/Data Center Plays

This space isn't slowing down. I'm buying more PSIX 0.00%↑ at these levels and watching for other quality names to get cheaper.

2. The Ethereum Treasury Strategy

More companies will announce Ethereum treasury moves, usually before market open. My play: buy immediately, sell when it hits 1x+ the Ethereum they raised. This should work through the crypto bull run until October-December, then I'm staying away from crypto based on historical patterns.

What I'm Building Next

I'm always looking for an edge, so here are two trackers I'm working on:

1. AppLovin Revenue Tracker

AppLovin makes money from games and ecommerce, and there's some public data we can use to estimate their revenue before earnings. Think of it like my TMDX 0.00%↑ tracker but for mobile gaming and ecommerce monetization.

2. Microcap Data Center Alert System

Here's the pattern I've noticed: as soon as any microcap company announces they're looking into data center solutions, the stock jumps 3-4x within a week. We saw this with TSSI 0.00%↑ , TGEN 0.00%↑ , and FTEK 0.00%↑ .

My plan is to build an automated tracker that reads earnings transcripts daily using LLM and sends alerts the moment any company mentions data center offerings. Imagine getting pinged before the market catches on.
