Sounds like you been had before. Unlike Retail Investors, Institutional Investors have definite exit criteria. So, unless that exit criteria is known, understood, and priced in, long-term commitment is just a guess on the part of Retail Investors.
I was quite interested that one such Institutional Investor was an Arbitrage company. Questions:
1. Are they short TMPS?
2. What is their exit criteria?
3. Why did they choose TMPS?
