Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
In contrast, professional fund managers (information here) do not want tips. They have dozens of good ideas of their own. They won't be sharing those ideas with you and they will not be expecting you to share yours. Instead, they ask about how you allocate money. "Which sectors and markets do you like and why?" The difference between these approaches is like night and day.
A stock split is when a company increases its total shares and is frequently done on a 2-for-1 ratio. So, if you own 100 shares of a stock priced at $80 per share and worth $8,000, after the split you'll have 200 shares priced at $40 each, and still worth $8,000. Stock splits occur when prices are rising in a way perceived to deter smaller investors. They can keep the trading volume up by making it easier for a larger buying pool to trade. If you invest in a stock, expect to experience a stock split at some point.
The solution to both is investing in stock index funds and ETFs. While mutual funds might require a $1,000 minimum or more, index fund minimums tend to be lower (and ETFs are purchased for a share price that could be lower still). Two brokers, Fidelity and Charles Schwab, offer index funds with no minimum at all. Index funds also cure the diversification issue because they hold many different stocks within a single fund.
One constant principle of investing is that markets fluctuate. Stock prices will rise and fall for a number of reasons: the economy, investor sentiment, political uncertainty at home or abroad, energy or weather problems, or even corporate scandals. This means market performance isn’t always predictable. That is why diversification, or spreading the investments in your portfolio among different asset classes and across different sectors within each class, is such an important strategy. Diversification is a time-tested way to manage risk.
Finally, you’re going to be looking for catalysts or roadblocks to growth for each company. This means looking in the financial news, reading analyst reports and management presentations. By this time in the process, maybe you’re only looking at four to six companies in a sector so this level of deep research won’t take more than a couple of hours.
