Commissions, taxes, and transaction costs are not included in any of these strategy discussions, but can affect final outcome and should be considered. Please contact a tax advisor to discuss the tax implications of these strategies. Many of the strategies described herein require the use of a margin account. With long options, investors may lose 100% of funds invested. In-the-money long puts need to be closed out prior to expiration, since exercising them could create short stock positions.

Options carry a high level of risk and are not suitable for all investors. Certain requirements must be met to trade options through Schwab. Multiple leg options strategies will involve multiple commissions. Spread trading must be done in a margin account.
