stock price > second level of its standard deviation

If P= price of a traded stock today
X is the daily return of the stock
And Y = average of x for 100 days + 1.96*(standard deviation of x for 100 days)
And z= average of y for 200 days + 1.96 *(standard deviation of y for 200 days)
And L = (P-Z)/Z
And the z score of L= (L-average of L for 100days) / (standard deviation of L for 100 days)
What statistically means if P > y and y > z and Z score of L > 1.96
