Buy S&p 500 ETF like VOO, SPY SPYM( avg gain of 10% a year). Or NASDAQ ETFs like SPLG, QQQM ( 15-20% a year). Or those with dividends like QQQI, GPIQ. SPYI, VYM, DGRO, SCHD. Then before December you know how much gains you have and can guestimate the taxes for gains. Sell equivalent of your losing stocks before the end of December to offset it. So that your net taxes for your stocks will be zero. Or better yet sell an extra 3000 and you can deduct it from your taxes ( if you are in the US.
Dig yourself out of the hole. A loss can be a win if you learn from it. I once bought a 76000 shares in penny stock for $3.50 in 2013 ( (FNMA) because of the hype. and watched it drop to .46 where is stayed for close to 10 years. I got burned and stopped trading. Until i opened my trading account early 2025 where its price improved.
My mistake was not investing in S&p 500 or Nasdaq funds from 2013 until 2025. I could have made up that money investing on the S&p and Nasdaq etfs. Time in the market beats timing the market. Watch Professor G in youtube or Call to Leap in Facebook. They make good videos on investing. Dont fall for high return funds as your goal is to make up lost money. Not a good time to buy to risk losing more.
I just got lucky as the penny stock is now close to $11. And i still own all of them. Account value from -40 k now fluctuates a little bit higher thanks to FNMA.
