The major issue is that it has a very small public float. The valuation is very high and there is a demand/supply issue. He is considering selling it but likes the space.

It's one year after it went public. ARM has rallied 10% in the last week, even slumping 6% today after reports of Apple iPhone's weak orders, which contains ARM's chips. He doesn't mind that, because ARM is up 175% since its IPO.

Shares slumped badly in recent weeks, but rebounded 7% today because is using their processors' design in the new iPhone unveiled today. But this was not news. Is up 146% since debuting last year. Huge upside. Buy dips.

He bought a small position and shares took off immediately. He's waiting for this to stabilize. There's much talk about its March 12 lock-up period to end.
