$134.99 is within $1.00 of every price we have recorded.
Across 23 days of record it has moved between $133.99 and $134.99. That is too narrow a range for today to be a good or a bad time to buy: waiting for the bottom of it would save $1.00.
This describes the prices we recorded. It is not a forecast of where this one goes next.
