This run tracked 149 articles and 51 active long/short calls, with an average signal return of +3.9% and a hit rate of +68.6%.

Executive Summary

This run tracked 149 articles and 51 active long/short calls, with an average signal return of +3.9% and a hit rate of +68.6%.

This is one in a recurring series that reviews LF0 Research’s own past ratings against what actually happened to the stock. The goal is an honest scorecard, not a highlight reel — full methodology and every call we’ve ever made is at /research-performance/.

If You’d Followed Every Pick

Beyond individual calls, here’s the model portfolio question: what if you’d put $1 into every Buy/Strong Buy pick the day we published it, and a separate $1 short into every Sell/Strong Sell pick? We’ve rated stocks at very different times — some calls go back to June 2026, others were made last week — so each pick’s $1 only joins its book on its own publish date. The return below is pooled value versus total capital actually deployed at each point in time, not a return measured from one shared start date.

  • Long book: +10.0% on 3 pick(s), $1 each. $3.00 deployed is worth $3.30 today.
  • Short book: +3.5% on 48 pick(s), $1 each. $48.00 deployed is worth $49.67 today.
  • Combined, long + short (i.e. every pick since we started): +3.9% on 51 pick(s), $1 each. $51.00 deployed is worth $52.97 today.

For comparison, here’s what the same $51.00 would have returned in a lump-sum buy-and-hold of the broad market since our first tracked pick (2026-06-09). This isn’t an identical methodology, since our capital went in gradually rather than all at once, but it’s the closest honest same-period reference point:

  • S&P 500 (SPY): +3.7%. $51.00 would be worth $52.90 today.
  • Nasdaq-100 (QQQ): +1.4%. $51.00 would be worth $51.71 today.

NLSTSell (Notable mover — worst active signal return)

What we said: – Rated sell because the stock prices in cleaner cash conversion than Netlist has delivered.

  • Strongest point: Q1 2026 revenue reached $104.9M, with EBITDA turning positive at $8.6M.
  • Biggest risk: operating cash flow was -$15.5M TTM, so earnings are not yet self-funding.
  • Valuation is rich at 5.3x EV/revenue and 48.7x EV/EBITDA.
  • I would raise my rating if quarterly revenue stays above $100M

What happened: Entry $2.44, latest $4.78, stock return +95.9%.

Why: Verdict: Incorrect so far.

SDGRSell (Notable mover — worst active signal return)

What we said: – Rated sell — valuation still prices in growth that cash flow has not earned.

  • Strongest point: the platform’s gross margin is 56.9% TTM.
  • Biggest risk: operating cash flow is -$126.9M TTM.
  • Valuation is rich at 3.9x EV/Revenue and 5.1x P/S.
  • I would only improve the rating if free cash flow turns positive and revenue growth re-accelerates.

What happened: Entry $17.40, latest $30.24, stock return +73.8%.

Why: Verdict: Incorrect so far.

CUESell (Notable mover — worst active signal return)

What we said: – Rated sell — cash burn and dilution risk arrive before clinical proof.

  • Strongest point: the platform’s IP base, with 161 issued patents and 308 pending applications.
  • Biggest risk: only $27.1M of cash at year-end 2025, with runway into Q1 2027.
  • Valuation is rich at 5.1x EV/revenue despite negative free cash flow.
  • I would move more bearish if the Q2 2026 IND slips or burn stays near $50.1M

What happened: Entry $26.96, latest $37.84, stock return +40.4%.

Why: Verdict: Incorrect so far.

Conclusion

Putting it all together: a $1 long book of every Buy/Strong Buy pick is at $1.10 (+10.0%) across 3 picks; and a $1 short book of every Sell/Strong Sell pick is at $1.03 (+3.5%) across 48 picks.

So far, the long book has outpaced the short book.

This is a running scorecard, not a finished one — both books will keep changing as more picks join and more tracking windows close. We’ll keep restating this comparison every week.
