Do plenty of research. You want your funds in a stock trending up.
If it is the most discussed stock on HC, or it has umpteen billion shares on issue, avoid it.
Put them all in a watch list. If it goes up by 10%, put some money on it. Look at a chart, work out the supports, place your stoploss based on support and don't lose more than 20%.
For new traders, only put 10% of your entire capital in speccies. 90% in solid big companies earning money and moving up, secure your portfolio cake, then ice it with a bit of speculation. For experienced traders, you know what to do.
