Here is a quick explanation of how a simple 100% capital guaranteed tracker bond works...
I found this very interesting, I wondered if this would also work for Joe Bloggs, so I applied it to any stock at random - I picked the S&P 500 and have neglected currency risk in this example.
Invest $14,532 in SPDRs (SPY) S&P 500 Index
Gross Expense Ratio 0.0961% - not really relevant to this example I think?
Dec'09 call SPY (currently $145.32) - Closest in the money call is:
145.00 FYNLO.X 19.40 Up 0.40 19.50 19.90 1,500 3,305
$14,532 exposure to SPY,
~$1,990 cost of option (taking worst of spread)
Capital left is $12,542
Interest at US interest rates in trading account, currently 4.84% (BM-0.5%) on $12,542
Apr 2007 to Dec 2007 @4.84% = $454 to $13,016
Jan 2008 to Dec 2008 @4.84% = $630 to $13,646
Jan 2009 to Dec 2009 @4.84% = $661 to $14,307
I am short by $225 - $32 = $193
_________________________________________________
Outcome A: With traditional pure stock purchase
With traditional investment of $14,532. If at outcome, value was $19,532,
gain is $19,532 - $14,532 = $5,000 profit, gives tax of $1,000
I have also neglected the spread on a purchase of $14,532 worth of SPY, so if the spread was
~1% then it would make up for the $193 difference.
Profit, approx $4,000
_______________________________________________
Outcome B: With this capital assured investment form
If at outcome, value was $19,532, gain is $19,532 - $14,500 Strike
= $5,032 - $1,970 option cost, so tax is $612
Tax on interest is approx $400, so total tax $1012 is approximately the same?
Profit, approx $4,000
Obviously with capital assured investments there is still the risk of a loss of interest over this period - approximately $2,000 in this example if the $14,532 was placed in a high-yield deposit account.
Please correct any errors or misplaced assumptions that I have made.
I suppose a question arises then, why do people not always invest in this way?
