"This is yet another case involving a city professional caught and jailed for abusing the market that employs him."
Between August 2000 and January 2013, Mr Clarke was employed initially as an assistant fund manager and, from 2006, as an equities trader.
In these roles, Mr Clarke received inside information about anticipated mergers and acquisitions, which he used to place trades using accounts in his own name and that of close family members.
The offences were committed over a 9 year period, with total profits amounting to over £155,000.
The FCA confirmed that confiscation proceedings will also be pursued against Mr Clarke.
In sentencing, Judge Korner QC described the offences as "pre-meditated, deliberate, and dishonest".
Mark Steward, Director of Enforcement and Market Oversight at the FCA, said: "This is yet another case involving a city professional caught and jailed for abusing the market that employs him. Insider dealing is increasingly detectable these days and, where detected, more likely to lead to terms of imprisonment and shame rather than glamorous profits and fame."
