See Cox, N. J. 2011. Stata tip 96: Cube roots. Stata Journal 11(1): 149-154. http://www.stata-journal.com/article.html?article=st0223 for some suggestions. In a sentence, cube root is suggested there as the simplest transformation that pulls in tails and treats values around 0 symmetrically. See also SJ-8-1 gr0032 . . . . . . .
