For the average person, sure. Past 90 years the S&P has done 9.8% annualized apparently. All daytraders aim for higher returns and some succeed.
I had a similar debate with a family member. He pointed out the average success rate and I replied with "I don't care about the average, I can do more and do it better". If it's arrogance or intelligence depends on the results. So far I've outperformed B&H. I can't speak for other people because I have no way of knowing how much effort they put into it.
You're also applying bias here as it's easier to recommend long-term investing after the markets have had a good run. In early 2009 barely anyone would've agreed with you and you might have thought differently as well.
Reminds me of the documentaries from the tech bubble when people were making fortunes in weeks and laughing about buy and hold. A year later many were bankrupt.
There's also absolutely no point in comparing to Berkshire. They use OPM to make these returns. Can't be compared to an at home trader or investor, as others have already pointed out.
Thank you for your reply.
I was brining up investing in Berkshire for 30 to 40 years as an example of a plan the the average guy who wants to be involved in the market would be far more likely to be successful with.
From your posts I can see you are not the average guy who sees himself as a soon to be daytrading wizard.
As I acknowledge in another post, for just the right person... yes...
The SOES Bandits cleaned up and many has a mentor. On a longer time frame, many of the Turtles (with a mentor) did well. Stanley Druckenmiller, Jim Simons, Blair Hull all starred out "trading".
