I sailed for two years aboard ultradeep rigs in 1988 and 1998 as O.I.M. ( offshore installation manager) and Captain, filling both positions each time.
SDRL(seadrill) long for 6 years, have added to position consistently, now 30 percent of portfolio.
PACD (pacific drilling) started buying 2 1/2 months ago, now 3 percent.
I realize this type of concentration is very dangerous for most people, but I watch my eggs (drilling companies) and basket (drilling industry) very closely, and it has been very good to me over the years.
I do all my investments without outside advisors.
