A $4M market cap and a tiny 470,000 share float: $WNW ripped 33.8% after the bell with zero filings, zero earnings, and zero news.
When a micro-cap with under 20 million shares in float gaps up 30% or more without a catalyst, the base rate is unforgiving. Across 2,411 historical instances of this exact setup, the stock closes red 70% of the time, delivering a median intraday decline of -10.5%.
Trading mystery momentum without checking the sample size is just donating capital to whoever found the exit button first.
