Back in Dec-2017, 
HRSTX instituted a strategy change.  The results since then have been quite consistent, with 93% positive monthly returns since then.   The worst monthly drawdown was -1.21%.   The annual Return %'s are somewhat bond-like. 
The Fund seeks to achieve its investment objective in three ways:
  (1) Premium Collection – the Fund collects premiums on options it sells.
  (2) Volatility Trading – the Fund may enter into positions designed to hedge or profit from either an increase or
     a decrease in index volatility.
  (3) Trend Following – the Fund may increase or decrease the balance of puts and calls based on trending market direction.

Any comments/opinions on this fund are appreciated.  Its one of the least volatile funds I've seen.

I haven't sold any of my HMEAX/HMEZX yet, though I am disturbed by the principal's past behavior. I also allocate funds to MERFX and BALPX in that space to keep exposure low for any 1 fund.
IQDAX was a reminder that even a mutual fund Mgr can dupe investors. Its a legit risk with these funds.
