Stock and bond traders can monitor the risk of their portfolio by assessing products and strategies.
For example, instead of directly trading S&P future, SPY and XLK are more palatable because of their smaller notional values and narrower daily movements. And stock traders can reduce their trade size and increase their probability of profit by shorting out-the-money options instead.
Similarly, treasury ETFs like TLT and the inverse TBT can be preferable to small accounts because of their smaller notional values and narrower daily movements. Again, trade size can by reduced by trading out-the-money options instead.
