Capstone: Building a Real Investment Plan

Sam already saw Chapter 1's own real, worked comparison — cash eroding to inflation versus growing when invested. With two genuinely different goals and two genuinely different time horizons, Sam decides to start now rather than wait, applying that same real compounding logic to both.

Sam rules out direct real estate investment (Chapter 2's own real illiquidity point — Sam is saving toward a property, not investing in one yet) and settles on a mix of stocks and bonds as the two real building blocks for both goals.

Rather than picking individual companies — and risking a real, Enron-style single-company collapse — Sam chooses broad, diversified funds covering hundreds or thousands of companies at once, directly applying Chapter 3's own real Modern Portfolio Theory material.

Rather than concentrating entirely in one country's own index — even the real FTSE 100 or S&P 500 — Sam chooses a globally diversified index tracking companies across many countries, spreading exposure to Chapter 3's own systematic risk category across multiple economies rather than just one.

Sam picks a low-cost index fund over an actively managed alternative, directly citing Chapter 5's own real SPIVA finding (54% of active large-cap funds underperformed in just six months) and its own real, independently-computed 30-year fee-drag example (roughly £16,582 lost to a 0.9-point annual fee gap).

Sam first confirms their own workplace pension contribution is already high enough to receive the full employer match — Chapter 6's own real, genuinely free money, left entirely separate from the £500/month below. The new £500/month itself goes into a Stocks & Shares ISA, chosen specifically because — unlike a SIPP — it stays genuinely accessible for the 5-year house deposit goal, not locked until pension age.

Sam splits the £500/month: £300/month toward retirement (a genuinely long, 30-year horizon), and £200/month toward the house deposit (a much shorter, 5-year horizon). Following Chapter 7's own real material, the house-deposit money uses a more conservative 50% stocks / 50% bonds blend — real, lower duration exposure — specifically because a real, 2022-style rate shock hitting close to the 5-year deadline would leave far less time to recover than the retirement pot's own 30-year runway allows.

Sam sets up automatic monthly contributions on payday, removing the real, ongoing temptation Chapter 8 documents — trying to time entries, chasing a recent hot fund (recency bias), or panic-selling during a real downturn. The contribution happens the same way every month, regardless of what the market did the week before.

Using Chapter 9's own real "100 minus age" heuristic, Sam's own age of 30 suggests roughly 70% stocks for money with a genuinely long horizon — applied to the retirement pot. The house-deposit pot deliberately runs more conservative than that heuristic alone would suggest, reflecting its own real, shorter 5-year horizon instead. Sam reviews and rebalances both pots once a year.
