There are advantages and disadvantages to day trading as there are advantages and disadvantages to longer term position trading. The obvious advantage to day traders is no overnight risk, you avoid the gap downs, you compound your monies at a faster rate because you compound it daily. On flip side, you also, lose monies faster, taxes are higher, commissions would be very high due to the volume of trades.
Now, longer term, you have less stress watching over your position, have larger gains because of time working in your favor and following the trend, taxes are lower. On the flip side, you will be riding back down any gains you have and could lose it to the wide swings, losses like gains will be larger, you compound capital at a slower rate because you are invested in that position a long time.
The choice is on you! There is no one size fits all because everyone's risk tolerance is different. Capital allocation is different. Time horizon is different. Pick the one that best suits you!
