Lock-Up Period
The window after an IPO during which insiders are barred from selling shares, typically 90–180 days. Its expiry can release a wave of supply that pressures the share price.
A lock-up period is the window after an IPO during which insiders — founders, employees, and pre-IPO investors — are contractually barred from selling their shares, typically 90 to 180 days. When it expires, a wave of supply can hit the market and pressure the share price.
Why it matters. The lock-up expiry is a scheduled, predictable event that moves newly listed stocks. For any Israeli company on the TASE or Nasdaq, it is a key date in reading post-IPO performance and insider conviction.
