I think that such returns are easier made with small amounts. Size effects.. Depends the strategy ... But the probabilities are the same. Scaling.
I think Pekelo's post wasn't a troll post, but just based on the general observation that there must 9999 of these type of journals "$XXX to Y,000,000 in a couple of months" here at ET that usually do not make it past the first page of posts. I see that yours is on page 2. So you are to be congratulated for taking it further than most. I think there probably are a few who could do something like this, though I wonder if any of them could do it publically. I'm reminded of @speedo's recent post elsewhere:
This thread will die in 3 pages like the last one. In order to so he will have to take risky bets. Why not start a thread "From $5K to $6K in one year" That is a 20% gain which is very good. If you can repeat that year over year people will throw money at you to invest for them. Actually if you made 10% a year consistently you are doing better than a lot of hedge funds With a 2% monthly return, your investment grows at approx 25-26% per year. Start with with $10,000 and obtain that return. Then every year invest 5,000 additional dollars. You will be near $1million in approx 15 years To grow 5K to 50K in 12 months means 19% a month. A bit unrealistic http://www.miniwebtool.com/exponential-growth-calculator/?n1=5000&n2=&n3=12&n4=50000
When dealing with small, miniscule even, acct sizes like $5k, you can leverage up like a maniac and go for ridiculous growth rates. I have seen 5k to 250 k for instance in a year (that guy did blow up a few times though!). So 5k to 50k is achievable, perhaps the odds are against it, but so what! Good luck (again, since i wished you good luck in your last thread). Post your trades. Don't be afraid for being wrong or of success. Just do it. If you lose, it is only $5k (i would stop and replenish the acct if you lose say $3k or $4k).
