hariri killing hits beirut shares shares in solidere  the lebanese company founded by assassinated former prime minister rafik hariri  fell 15% in renewed trading in beirut.  the real estate firm  which dominates lebanon s stock exchange  ended the day down at $8.08. traders said there was some panic selling during friday s session  the first since a three-day market closure to mourn the death of mr hariri. beirut s benchmark blom stock index closed down 7.9% at 642.80.  solidere  in which mr hariri was a major shareholder  was the major drag on the index. the company owns much of the property in central beirut  which it restored and redeveloped following the end of lebanon s bitter 15-year civil war.  solidere should be above $10 but because of this disaster it is falling   said one trader.  if solidere drops much lower i would consider it a buying opportunity. this is a very big company held by many lebanese.  critics had accused mr hariri of using lebanon s post-war reconstruction drive for his personal financial gain. but his assassination on monday sent shudders through lebanon s business community  which saw the billionaire tycoon as the country s best hope for economic revival. solidere posted profits of $12.5m in the first half of 2004  and its shares had been gaining in recent months.
