With our trial, the first month of service is totally free. You may cancel at any time during the trial month and will not be billed. All new trial accounts begin at our Extra service level, but you may upgrade or downgrade at any point during the free month. After that period, we will charge your credit card for another month of whichever service level you last selected. Refunds are available only for whole months of remaining service and do not apply to data plans.
Weighted Alpha is a measure of how much a stock has risen or fallen over a one-year period with an emphasis on the most recent price activity. A stock whose price has risen over the one-year period will have a positive Weighted Alpha. A stock whose price has not changed in the period will have a small Weighted Alpha and a stock whose price has dropped over the period will have a negative Weighted Alpha.
