Sure sir. Short squeezes occur when the float is locked as you've seen, and short trading occurrs. However, it doesn't ever need to be 80-90% of the float. A short squeeze occurs because those shorts don't see any point to cover in the near future. A 20% short squeeze is simple. That in fact is a great % of the float to squeeze. If that float realizes that there's no backing down in the upward trend, then they'll have to cover. It's simple. 20% of any foat will cause a HUGE squeeze. If an MM sees an imminent upward trend what else can they do?
