IMO the penny world is FULL of nonsense, that is part of trading penny stocks. I personally am not bothered by Sierra since it seems to be fairly accurate in both large cap stocks down to pennys which is rare. Often you find penny promoters that are only right in penny plays because they have a big following that can move low volume stocks, but they cannot trade large caps to save their lives because their newsletters do not have enough members to move a stock with any volume lol.
Another thing to note is that Sierra called a big drop in HUSA when I was long and I did not believe them but it happened, so ridiculous concept or not, I should have listened to them then, I should have listened to them on AAPL, and other stocks as well. For now it seems they are most insistent on HUSA so just happy they are on my side this time and I am hoping their track record continues to impress with regards to HUSA.
