There are plenty of investment strategies that have done nothing or even gone down by being wrong on a guess of what the market will do and failing to be diversified. Someday (maybe many years from now) they may be right again and will make money when others lose.
I suggest that OP think of his experience as a very expensive lesson. Let's assume the advisor is completely honest, I guarantee there were advisory fees, there were high expenses for the funds and maybe other fees or loads, all those folks ate quite well on the fees while OP got little in the leftovers.
Every single advisory firm claims they will beat the market which is obviously crazy. The actual statistics show it looks just like random chance - sometimes one is hot and sometimes cold. Over time, your best path is the simplest - buy the market and minimize fees.
So buy a Total Stock Market ETF from Vanguard, Fidelity or Schwab. Add a Total Bond ETF with whatever percentage of your money you don't want in stocks. Rebalance back to your desired stock / bond allocation once a year or when the allocation drifts substantially from your target. That really is a great portfolio, but the entire advisor industry needs to make it sound complicated so you will let them take your money in high fees.
