When talking about investments/trading, roughly how many % return per year is considered lousy/average/good ?
There’s no one answer to this: it depends entirely on what your benchmark is. So if you’re going to go out and trade, make sure you pick an appropriate benchmark, and then be absolutely ruthless when you compare yourself to that benchmark: “is all this extra effort making me more money than I would have made if I’d just bought the index and gone to the pub?”.
Make sure you pick a sensible benchmark, too—a benchmark that reflects the universe of things you trade
Are you trading US stocks? You’re probably trading large-caps, so use the S&P 500 as your benchmark.
Are you trading SG stocks? Use the STI.
Are you trading long/short stocks? If you’re doing a 130/30 style thing, where you’re net long, then your benchmark is still the equity index; but if you’re doing market-neutral long-short, you should benchmark to short-term cash instead.
Are you trading commodities? Benchmark to the price of the thing you’re trading: is all your active trading giving you any benefit over just buying the thing and sticking it in a safe?
