Indian + US portfolio tracking: one view, two markets

The evening one holding had two answers

Rohan’s US brokerage screen was in dollars: twelve shares, bought at an average of $140, now quoted at $161. His own spreadsheet, built to feed a household total, was in rupees. It showed a larger gain. He assumed one of them was broken. Neither was. The dollar screen was measuring the company. The rupee sheet was measuring the company and the currency at once, without saying so.

That is the whole difficulty with holdings abroad. It is not a technical problem. It is a labelling problem. A single percentage cannot answer both “did this business do well?” and “what is this worth in my life in India?” The fix is not to pick a favourite number. It is to keep both, and to know which one you are quoting when someone asks over dinner.

Keep the buying currency and the reporting currency apart

Enter US quantity and average cost in dollars. Work out the holding’s value using its dollar price. Convert only the resulting value into rupees, and only when you are building a combined total across both markets. This order matters. It prevents the most common cross-border error: mixing a rupee purchase amount with a dollar market price. That mix produces a number that means nothing at all.

Two words help here. Dollar price is what the US share actually trades in. Rupee total is what you use for the household view. Keep both. Do not mix a rupee buy amount with a dollar market price. That mix produces a number that means nothing.

• Native value = quantity × US market price, in dollars
• Reporting value = native value × the USD-INR rate on the same date
• Combined allocation is calculated only after every holding is in one reporting currency
• Keep the rate you used and the date beside the figure, so the total can be re-checked later

Fifteen per cent in dollars, about twenty in rupees

Rohan’s twelve shares cost $140 each, so $1,680 went in. At $161 they are worth $1,932. In dollars that is a gain of $252, or fifteen per cent. Rounded prices, brokerage and remittance charges left out, and one valuation date for everything.

Now the rupee view. The dollar cost 82.40 rupees on the day he bought and 86.10 on the evening of the dinner. The invested amount becomes about ₹1,38,432 and the current value about ₹1,66,345. That is a gain of roughly ₹27,913, or about twenty per cent. The company contributed fifteen points of that. The weaker rupee contributed the rest. Rohan had not become a better stock picker between June and August. The currency had moved while he held the shares.

Reading the two side by side is the skill. The dollar number tells him whether the investment idea is working. The rupee number tells him what the holding is worth against a school fee or a home loan, both of which are quoted in rupees.

When the rupee goes the other way

Currency movement is not a bonus, and it does not only move in a helpful direction. Keep everything else the same, but suppose the dollar had cost 79.50 rupees on the evening of the dinner instead of 86.10. The same $1,932 would translate to about ₹1,53,594. That is a gain of roughly ₹15,162, close to eleven per cent in rupees, against the unchanged fifteen per cent in dollars.

Same company, same share price, same twelve shares, a clearly different rupee result. That difference matters. A return converted into rupees is not a verdict on the investment. Nothing here says a strong or weak rupee is good or bad for you. It says the two effects must be separated before you draw a conclusion, especially if the conclusion is about whether to buy more.

Currency also changes your allocation

This is the part Rohan had not thought about at all. His combined portfolio was about ₹14,00,000, with the US holding at ₹1,38,432 when he bought it, a little under ten per cent. After the dollar strengthened, the same twelve shares sat at ₹1,66,345, or nearly twelve per cent of a portfolio whose Indian holdings had barely moved that month.

His US weight grew without him buying a single extra share. Currency alone can change the shape of a portfolio. Anyone tracking a target geography split needs to know whether a change came from prices, from purchases, or from the exchange rate. Three very different causes can look like one percentage on the screen.

What to write down on remittance day

The evening ended with a short checklist in Rohan’s notes app, used every time money leaves India. It exists because remittance details are hard to rebuild a year later. The tax and cash-flow story is also separate from the holding’s performance story.

Rohan also stopped treating geography as a clean label. A US-listed company can earn much of its revenue in Europe or Asia. An Indian company can earn a lot abroad. A simple India-versus-US split is still a practical first view of concentration. It is not the last word on where your economic exposure actually sits.

• The rupee amount that actually left your bank, including bank charges and any tax collected at source
• The exchange rate the bank used, which is rarely the rate quoted in the news
• The dollar amount that landed in the brokerage account after fees
• The trade date, the dollar price and the quantity, kept in dollars

Rohan’s Sunday, six months later

His portfolio now shows both columns without being asked: the dollar value for each US holding, and the rupee contribution to the household total. Westro can display US stocks and US exchange-traded funds beside Indian assets, with the total shown in rupees or dollars. The same holdings can be read through either lens without re-entering anything.

Two cautions come with that convenience. Market prices and exchange rates may be delayed, so confirm figures before acting on them. Your brokerage and bank statements remain the source of truth for trades, charges and tax records. And when the dinner-table question comes round again, Rohan now answers it in two sentences instead of one: up fifteen in dollars, about twenty in rupees, and here is why those are different numbers. This guide does not tell you how much of your portfolio belongs abroad. That depends on your goals, obligations, and how much variability you can live with.
