Grade = how their written analysis reads (A best). Trader score = how their last-20 timestamped calls performed vs SPY. · Analyst brief as of 2026-06-22.

Their picks, scored

Across their last 5 scored bets: 100% hit rate, +0.85% mean alpha, trader score +1.00. Their last-14d mentions, direction-adjusted, have moved -1.5% since posting (mean over 3 mentions with price data).

Crypto market structure and portfolio construction dominate

Choffstein is focused on crypto derivatives market structure, especially perps, leverage, Hyperliquid, Lighter, and licensing pathways, with a disclosed private Lighter investment. The distinctive read is constructive on high-leverage perps when execution and counterparty structure are sound, while skeptical that US access is straightforward if perps are treated as swaps. Public-market ticker content is sparse, limited to BTC market-structure framing and SPY volatility/base-rate context rather than directional equity calls.

Direction this week

The author’s concentration sits in crypto derivatives market structure, with repeated discussion of perps, leverage, licensing, Hyperliquid, and private Lighter. There is no public CALL_DIRECTIONAL trade and no clear flip; the only disclosed position is a held private Lighter investment. Public ticker exposure is light, with BTC used for crypto market-structure context and SPY for volatility, leverage, and equity-beta portfolio framing.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
